"Team Yellow... Do you remember when we met last time?" Wan Baoming walked a little further, holding his phone in his hand, his head drooped lower than his shoulders, and his waist was playing.

It is not easy for the deputy director, and there are not many things that can be taken out, but Huang Qiangmin has a very big appetite.

There was a trace of crystal clear in Wan Baoming's eyes.

It's too difficult to do something.

Jiang Yuan could not see Comrade Wan Baoming's eyes and expression. He sat on the other side of his study, almost 20 meters away from Wan Baoming's choice of the corner of the wall, and even Wan Baoming could not hear clearly.

Of course, Jiang Yuan was not interested in listening to him quarrel with Huang Qiangmin.

He turned on the computer himself, put the fingerprints that Wanbaoming brought in, and first used Photoshop to handle it simply.

After making fingerprints for a long time, Jiang Yuan was able to make some judgments about his own before matching them with the software. Whether the fingerprints in the middle and the similarity of the fingerprints in the middle can be predicted.

In general, if fingerprints with too much incompleteness are not processed first with image software, it is possible to match any monsters and monsters.

Of course, it is also possible to match the correct fingerprint, but it is not interesting to play this probability game for those LV2-level trace detectors may only use this method to cover the task when doing super difficult fingerprints, but for Jiang Yuan, he has already surpassed this level.

He has to be at least at LV4.2 now, and even the 0.2 behind him will have to beat up a lot of people.

If you make too many difficult fingerprints and always succeed, this kind of experience is valuable in itself. Just like an ordinary person who has been working in the position of president for a long time, he can gradually figure out some experience.

The fingerprints that Wanbaoming took this time are a bit too incomplete. According to Jiang Yuan's experience, now they are thrown into the fingerprint software to match, and the answers they get are equivalent to random.

It's nothing strange. If it weren't for the difficulty exceeding the level of LV3, why would Wanbaoming be so humble?

A few minutes after Wan Baoming and Huang Qiangmin were on the phone, Wan Baoming came over with his cell phone and whispered: "Jiang Yuan, your team Huang's phone number."

"Okay." Jiang Yuan took the call.

"Jiang Yuan, how are you resting? Are you tired?" Huang Qiangmin asked with a smile on the phone.

"It's okay. I built a wall for a day today and I was sweating a little." Jiang Yuan said.

"It's good to sweat, it's good to sweat, and it's good to be healthy." Huang Qiangmin laughed and said, "Wan Baoming gave you another fingerprint? Is it difficult for him to get a snake and stick. "

"High. The probability of making it directly is not high." Jiang Yuandao.

"Oh, can you win? Can you win?"

"That depends on whether Curry has fingerprints." Jiang Yuan paused and said, "Even if Curry has fingerprints, it depends on the quality of Curry's fingerprints..."

"How sure are you able to do it if you give a number?"

"Sixth." Jiang Yuan looked at Wan Baoming, but he didn't hide it too much.

Based on the keyword analysis alone, Jiang Yuan felt that Wan Baoming must have consulted fingerprint experts from ministries and commissions.

But to be honest, fingerprint experts from ministries may not be at the level of LV4. With powerful experts, there must be more than LV4 levels, and maybe there are LV5 bosses.

But experts also talk about probability and investment.

Can Wanbaoming hire a strong enough fingerprint expert and ask the other party to devote himself to it?

It's probably very difficult.

The bigger thing is that the other party helps to see it, and if he fails to win in a short period of time, he gives up.

After all, experts from ministries and commissions are very busy. There are more than 30 provinces like Shannan Province in the country. Even experts may not be able to make one in a week.

It’s like during the fingerprint battle, it’s normal for experts at the Shannan Provincial Department. The entire battle lasted for 15 days, and it would be better to see about 100,000 fingerprints than winning a few.

The intensity and importance of the battle are completely different from daily help.

Jiang Yuan only said to Huang Qiangmin: "This fingerprint is done normally in the province, and there is no hope."

Huang Qiangmin then understood and said happily: "Okay, then you give your phone to Wan Baoming, and I'll ask him to make up for the expenses of the previous fingerprint."

Jiang Yuan smiled: "It took me more than two hours to finish my fingerprint."

"I've told me this, and it has to be based on computing power." Huang Qiangmin said confidently: "Please give Wan Baoming your phone, don't feel sorry for him. Changyang City is so rich. A little bit leaked in the crack of his fingers is enough for our small county town to struggle for 10 years."

Jiang Yuan laughed and returned the phone to Wan Baoming.

Wan Bao Mingzhen took it seriously, put it solemnly in his ears, and said, "Captain Huang, I, Xiao Wan..."

While talking, Wan Baoming continued to walk into the corner.

Jiang Yuan sat back in front of the computer. Before the host started roaring, Jiang Yuan could vaguely hear some mysterious keywords:

"Please."

"It's really worrying."

"Yellow Team~"

"You're going to help..."

...

After a long time, Wan Baoming delivered his hot phone to Jiang Yuan.

Jiang Yuan: "Hey. Team Yellow."

Huang Qiangmin: "You can do it for a while. I will ask them to send two of them to do training for us. In addition, let's lend them some old equipment and other things. I still keep the hole. When you look back, what do you like and what you want, tell me."

Jiang Yuan said a little embarrassedly: "Okay."

"Okay, you can drive hands-free." Huang Qiangmin said.

Jiang Yuan then took down his phone and turned on the hands-free one.

Huang Qiangmin's voice came out: "Jiang Yuan, Director Wan's task, you can do it well. You have two days left for the holiday here, so don't take a break, and you're going to go back to work. After finishing your work, you're taking a break. Changyang Criminal Science Center has also helped us with many cases before. This time you have the opportunity to cooperate, you have to cherish..."

"Yes." Jiang Yuan responded in a regular manner.

"Director Wan, then Jiang Yuan will be given to you. Young people are ignorant and have any bad things to do. If you have any questions, just come to me and I will criticize him..." Huang Qiangmin ended the call in a nagging manner.

Wan Baoming put away his phone and sighed: "Your team yellow is not as easy to talk to as before."

Jiang Yuan just smiled and said nothing.

It is likely that borrowing someone else's big green ox to plow the land is different from borrowing a cat to catch mice.

The mouse moved, and the computer started to scream.

In terms of image rendering, the computers with a high configuration all have the same sound, and this one is like that, right?

"Director Wan, is it easy to introduce the case?" Jiang Yuan took this time and asked Wan Baoming.

"This is the case of Maixin Electronics Factory last year. A famous female worker was pushed down on the roof. At first, she thought it was suicide. Later, a witness said she saw two people on the roof, and there were pushing and shoving actions..." Wan Baoming described the scene, and then focused on the evidence:

"The early police dispatch was actually a little problem. Because I thought it was suicide at first, the protection on the spot was not very good. The factory security guards and workers all ran to the top of the building."

"Secondly, there are only eyewitnesses and lack of surveillance videos. Because they are all wearing work clothes, it is not easy to judge the murderer."

"The third is that the workers in the factory are not very familiar with each other. This Maixin factory is a model of recruiting people as they employ people. It is to sign a large OEM order and recruit a group of workers to do it. After almost all, they will be fired. When there is a big order next time, they will be recruited. Therefore, it is not easy to solve the case based on social relationships."

Jiang Yuan listened to Wan Baoming's introduction and asked: "The only evidence is the fingerprint on the clothes?"

Wan Baoming sighed: "The problem now is that the fingerprint on the clothes has become a reverse evidence. The suspects that the detectives focused on asking were all eliminated by the fingerprint on the clothes..."

Jiang Yuan couldn't help laughing and asked again: "Whoever everyone in the factory should have fingerprints?"

"It was picked. When something happened, the factory closed the door directly, and the video surveillance of import and export was also complete."

Jiang Yuan couldn't help but nodded. In this way, the problem of fingerprint library was actually solved.

From the perspective of a trace detection, this is a perfect fingerprint comparison environment. You can compare it by just making fingerprints.

Thinking of this, Jiang Yuan frowned again and said, "The core issue is matching fingerprints. Last year's case really can't match. It's always possible to match one person by one..."

Wan Baoming couldn't help but smile and hurriedly covered it up, saying, "I just said that the factory belongs to Maixin. You may not know much. The factory received a large order at that time and was in a state of full workload. There were nearly 30,000 workers in the factory."

Jiang Yuan suddenly realized.

It is definitely unrealistic to compare fingerprints one by one for large factories with tens of thousands of people, especially the state of this fingerprint is still so poor.

"What did you use to extract fingerprints at that time? Did you 502?" Jiang Yuan looked at the fingerprints and gradually entered the state of comparing the lower fingerprints.

Wan Baoming understood Jiang Yuan’s implicit meaning and smiled bitterly: “Yes, 502 is scattered.”

Similar to the smoke display of ninhydrin, the 502 gel smoke display method is also a solution to reveal the sweat-depressed fingerprint after applying chemical reagents.

Similarly, all similar solutions actually have a problem that people rarely talk about, and it is easy to cause flaws when operating.

The criminals had already accidentally left their fingerprints. If the fingerprints were broken and displayed incompletely, they would definitely not give another copy.

Just like the fingerprint in front of you, it is so broken that the trace inspection will be matched with a bitter match. Usually, you have to complain about the fingerprint extraction. Usually, those who are scolded are also checked immediately.

Jiang Yuan used image software to slightly adjust his fingerprints and gradually gained ideas.

When he became energetic, he was too lazy to pay attention to Wanbaoming and said, "If you don't play with dogs, you will have a result. I'll tell you again."

"Okay." Wan Baoming responded, and then he felt a little moved: "Am I waiting here?"

"Then... if you have something to do, go ahead and do it." Jiang Yuan naturally didn't care.

Wan Baoming hurriedly said, "I don't mean that, I mean...uh, will there be a result today?"

"It's possible. Now we mainly need to process images. This fingerprint is taken from cotton clothes. The natural fibers of cotton are spiral twisted. The fiber section looks like a waist and are prone to fluff. This is the main reason why the sweat-subtle fingerprints are not expressive enough..." Jiang Yuan briefly explained to Wan Baoming.

Wan Baoming looked at Jiang Yuan and said, "I have also done trace examinations. I understand the truth, but..."
